IMPROVED MACHINE POR SPLITTING- WHALEBONE.

lhe Schedule referred to in these Letters Patent and making part 0f tlie same.

To all whom it may concern Beit known that I, NATHAN GODDARD, ofBoston, in the county ofSui'olk, and State of Massachusetts, have invented new and useful Improvements in Machines for Splitting Whalebone; and I hereby declare that the following is a full and exact description of the same, and I refer to the accompanying drawings, and to vthe letters of reference marked thereon, making part of this speciiicatiomof which- Figure 1 is a perspective view of the invention and improvements, with part of one clamp removed.

Figure 2 is a section of a part of the machine, showing the application and arrangement of certain parts.

Figure 3 is a section of apart of the machine, showing the guide and its parts applied to the same.

The letter A represents the frame of the machine.

B B, the clamps.

au, &o., the side adJusting-screws.

b l), &c., the top adjusting-screws.

d (l, 87o., the rollers.

k 7.', 86C., the knives.

s s, &c., the spaces.

i p, the rollers of the guide.

n n., slots iu the sides of the guide.

m and w, springs attached to frame and guide.

Thel drawings exhibit a quadrangular frame, a portion ofthe top of which is an inclined plane, and upon this plane is arranged a series of knives, clamps, rollers, screws, a guide, 85e., all combined in a machine for the purpose of splitting whalebone and like material into strips.

The invention embraces improvements upon a device for the same purpose, patented by this applicant, of date November 5, 1867; and in order that others may better understand and be enabled to manufacture the saine, I will explain the improvements.

The series of knives k k, 85o., is arranged, as seen in tig. 1, one above or beyond another, s'o that when a piece of whalebone is placed iu front of the knives and pushed under the roller l, or against the first knife .in the series, the same will be split into strips of uuiform thickness, according to the height between the knives, this height being regulated by adjusting-screws beneath the rollers d d, Sto., the heads of the screws being at the bottom of the machine, ahd not shown in 'these drawings. This arrangement of the series ot' knives is precisely the same as in theaforesaid patent.

But in order to sharpen the knives when necessary, I have constructed the improvements thus:

B B represent clamps, as seen in fig. 1, rectangular in form, and made so as to fit closely upon the frame A.

They have screws, b b, 80e., passing through the top, and pressing upon the upper surfaces of the knives It 7c, &c., and at the sides. are screws, a a, &c., passing through and into the spaces s s, 8vo., at the back of the bevelled part of the knives. The same is clearly seen in fig. 2.

The screw a adjusts the knife over and to the rollerk, and the screw l1, with the clamp B, keeps the knife down, and from twisting and warping. The knife may in this way be laken out and ground, and readjusted, till the blade is nearly worn out. It is more precisely adjusted over the roller than iu the aforesaid patent, is simpler inform, and more easily made.

The clamps B B are guides, for keeping the whalebone upon the sharpened parts of the knives.

In pushing t-he whalebone through or against the knives, it is necessary to keep the same down upon the plane, before the knives, with the hand, in the aforesaid patented machine.

I have constructed a guide, which is seen apart, inl

a vertical section of a part of the machine, in tig. 3.

'This consists of a pair of bars and rollers, slipped on the lower end of the frame A, as far as or near the clamps B B. At the upper part isa roller, l, at the lower part the roller p, both being fitted into the side pieces ofthe guide.

The guide is fastened to the machine by two screws, on the two sides of the same, and the two side pieces ofthe guide have slots, n n, in which the screws ivork, as seen in fig. 3. The slots enable the guide to work up and down when needed.

There are also springs, m andw, seen in said fig. 3.

When the whalebone is to be .pushed against the knives, push up the spring w this carries the guide, and it will be held by the notch in the springm. Push back the spring fw, and the guide will drop upon and hold the whalebonefor steady it. f

Being made with a roller at the top arid bottom, and slots at the side, it has anoscillating or side movement,l or may have. This will enable a diamond-shaped piece of whaleboue to pass under the roller l without didi-.- culty.

When in use, the machine is secured in a vise,'or otherwise fastened, and the operators stand, one pushing in the whalebone, the other seizing the same, as it passes through, with instruments, and pulls through the strips of any length, and with great rapidity and ease, thereby saving, by use ofthe machine, much time and labor. l

The improvements are novel, and of great practical utility. g

- I claim as my invention, and d'esire to secure by Letters Patentl 1. rlhe rectangular 'clampv B, provided with the screws a a and b b, in` combination with the knives 76 k and rollers d d, all the parts constructed substantially as described and for the purpose specified 2. In combination with the above, the presser-roller l, constructed and operated as shown and described.
